After many sleepless nights in order to decide what to buy I finally want to ask this forum for advice.Taking my present setup into consideration it would appear that I should well look at the Roland E600 not only for compatibility but also for good sound. On the other hand I also like the PSR 740 as well as the price....I cannot afford more than approx. R12000.00 after discount.(I am in the RSA) I want to use any new keyboard in conjuntion with Cakewalk and my pc. I tried sound modules but feel that my SC88 pro is doing the job.Also the arranger on some keyboards will assist in preparing sequences quicker.Please give me some advice or opinions...Thanks a lot...Hein
